About This Architecture

FurLink's three-tier web application architecture separates public-facing, application, and secure backend layers with dual firewalls, WAF protection, and CDN acceleration. Public users route through an external firewall and WAF to a load balancer distributing traffic across three PHP application servers, which connect to a secure backend network housing MySQL primary and replica databases plus Redis cache. Admin and IT staff access the infrastructure via VPN gateway and admin firewall, with dedicated monitoring and dashboard visibility. This design enforces network segmentation, reduces blast radius, and ensures high availability through load balancing and database replication. Fork and customize this diagram on Diagrams.so to adapt firewall rules, add additional app servers, or integrate your own monitoring tools. The DMZ tier isolates public-facing components from internal systems, a critical pattern for compliance-heavy applications.
